Problems solved by technology

Therefore, when the available bandwidth of the air interface is greater than the backhaul bandwidth of the backhaul circuit, the data transmitted by the user equipment on the air interface will be blocked at the AP, resulting in invalid user data, which will increase the retransmission rate of the user equipment and make telecom operators Reduced communication link reliability under commercial conditions

Abstract

The invention provides a method for adjusting data transmission rate and AP (Access Point) equipment, which relates to the field of communication and is capable of transmitting the data at the lowest data transmission rate so as to reduce the waste of the data transmission rate. The method comprises the following steps of obtaining theoretic transmission bandwidth used for communication of each of user equipment in each cycle period; determining first user equipment which has a transmission bandwidth smaller than the preset CB (Commit Bandwidth) lower limit and highest retransmission rate; obtaining an available bandwidth of an air interface of WLAN (Wireless Local Area Network) according to the transmission bandwidth of each of user equipment; if the available bandwidth of the air interface is greater than a preset return bandwidth, reducing the data transmission rate of the first user equipment at the air interface. The bandwidth setting method and the AP equipment, which are provided by the invention, are applied to communication of WLAN.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data transmission rate adjustment method and equipment and AP equipment. Background technique [0002] With the popularization of smart phones and portable devices supporting WLAN (Wireless Local Area Networks, wireless local area network), WLAN devices have begun to be used for broadband wireless access in telecom operators. For this reason, APs (Access Points, Access Points) begin to enter the network of telecom operators in large numbers. Since the AP applied to the small wireless local area network can complete the communication between the connected user terminals by itself, the resource occupation on the wireless port will be relatively large. Coupled with possible interference from other systems, the wireless port itself is more likely to become a transmission bottleneck. Therefore, the excessive data transmission rate of the user equipment may be the cause of the com...
